# emhttp_event script (a work in process).

# This script is called by the emhttp process as a result of various events that take place.
# The /var/local/emhttp/*.ini files are updated immediately preceeding each event.
# Caution: the 'emhttp' process will hang until this script completes!

# The first argument to the script is a string indicating the event:

# driver_loaded
#   Occurs early in emhttp initialization.
#   Can also occur as a result of init-config and device slot change.
#   Status information is valid.

# starting
#   Occurs at beginning of cmdStart execution

# array_started
#   Occurs during cmdStart execution.
#   The 'md' devices are valid.

# disks_mounted
#   Occurs during cmdStart execution.
#   The disks and user shares (if enabled) are mounted.

# svcs_restarted
#   Occurs during cmdStart execution.
#   Occurs as a result of changing/adding/deleting a share.
#   The network services are started and may be exporting different share(s).

# docker_started
#   Occurs during cmdStart execution.
#   The docker service is enabled and started.

# libvirt_started
#   Occurs during cmdStart execution.
#   The libvirt service is enabled and started.

# started
#   Signals end of cmdStart execution.

# stopping
#   Occurs at beginning of cmdStop execution

# stopping_libvirt
#   Occurs during cmdStop execution.
#   About to stop libvirt.

# stopping_docker
#   Occurs during cmdStop execution.
#   About to stop docker.

# stopping_svcs
#   Occurs during cmdStop execution.
#   About to stop network services.

# unmounting_disks
#   Occurs during cmdStop execution.
#   The network services have been stopped, about to unmount the disks and user shares.
#   The disks have been spun up and a "sync" executed, but no disks un-mounted yet.

# stopping_array
#   Occurs during cmdStop execution.
#   The disks and user shares have been unmounted, about to stop the array.

# stopped
#   Occurs at end of cmdStop execution, or if cmdStart failed.
#   The array has been stopped.

# poll_attributes
#   Occurs after each time emhttp polls disk SMART data.
#   Note that if array is not Started, emhttp will not spin down any disk, but emhttp will
#   still poll SMART data (for spun-up devices) and generate this event.
